NVIDIA-SMI 525.105.17 Driver Version: 525.105.17 CUDA Version: 12.0  
deepstream-6.2

{  
“version” : “4.0”,  
“id” : “2197”,  
“@timestamp” : “2023-06-08T08:29:24.927Z”,  
“sensorId” : “cam0”,  
“objects” : [  
“0|1232.87|153.384|1384.16|364.948|jet\_bridge\_disconnected”,  
“2|844.068|172.347|1094.17|535.746|airplane\_front”  
]  
}

in above format , i want to add specifically description variable by fetching from dstest5\_msgconv\_sample\_config.txt ,  
for that what changes needs to be done in generate\_event\_message\_minimal function of eventmsg\_payload.cpp

output should looks like this  
{  
“version” : “4.0”,  
“id” : “2197”,  
“@timestamp” : “2023-06-08T08:29:24.927Z”,  
“sensorId” : “cam0”,  
“Description”:‘Aisle Camera’  
‘location’:45.293701447;-75.8303914499;48.1557479338

“objects” : [  
“0|1232.87|153.384|1384.16|364.948|jet\_bridge\_disconnected”,  
“2|844.068|172.347|1094.17|535.746|airplane\_front”  
]  
}

**There is no update from you for a period, assuming this is not an issue any more.**

**Thanks**

nvmsgconv plugin and low level lib are opensource, you can modify nvmsgconv.cpp in deepstream sdk, after modifying, you need to rebuild the code and replace the old lib.
